LINE-CASTING STOP DEVICE FOR TYPE-CASTING MACHINES.

Specification of Letters Patent.

Patented Jan. 12, 1915.

Application filed January 29, 1914. Serial No. 815,151.

T rzZZ whom it may concern Be it known that I. STERLING B. Emsronn, acitizen of the United States, residing at Berkeley. in the county ofAlameda and State of California, have invented new and usefulImprovements in Line-Casting Stop Devices for Type-Casting Ma chines, ofwhich the following is a specification.

This invention relates to linotype and typographic machines, andparticularly to means for controlling the operation of the pot pumplever. I

The object of the present invention is to provide a simple, practicable.reliable. semiautomatically operable controller whereby the operation oithe pot pump lever can be readily controlled.

It is a further object of the invention to I provide a simple controlleror device, operable by the operator. for interrupting the pressuremovementot the pot pump lever of the machine when it is desired toprevent the casting of a slug from a line of matrices which is passingto the vise oi the mach ne: and to provide such a controller as willoperate automatically to permit the operation of the pot pump leverwithout requiring the attention of the operator of the mach ne to bringthe device into operati e position.

Due to accidental operation of the kevs of the machine by an operator,or due to the transposition of matrices and spacebands during assemblagein the assembler, it frequently happens that a line being compiled inthe assembler will be in improper order, with the result that whenpassing to the casting positionin the machine an improper slug is cast.and this, when finally deposited in the stick, unless withdrawn by theoperator. passes into the form and escapes detection. with the resultthat the error is not found until the column has been printed.

It is the principal purpose oi the invention to provide a simple meansby which the operator can readily prevent the casting of a miscompiledline from the erroneously setline of matrices in the vise, thusrelieving the operator of the close attention which he must giveordinarily to the action of a machine-in setting a line of matrices andpermitting him to operate free of this burden, giving all of hisattention-to avoiding the necessity of his breaking mo-v the copy andtion at the keyboard, when operating, as is necessary when he must stopto remove the hot pi line from the stick.

Another advantage of my present invention is that by its use there is nodanger of squirts caused by matrices getting im, properly positioned inthe line being cast, as by the simple actuation of the controller by theoperator, the casting of the line,

though it may have been assembled in the device, is entirely avoided.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which Figure 1 is a frontelevation, showing diagrammatically the parts of a linotype machineinvolved in the present combination. Fig. 2 is a. planview of theoperating lever of the stop lever. i

In Fig. 1, 2 represents the front end of the usual operating lever whichoperates the stop lever 3. Fig. 2, which is adapted to be interposed inthe downward path of the pot pump lever, indicated at 4, the function ofwhich is to eject metal from the metal pot to cast a line from a line ofmatrices assembled in the vise. One of the jaws of the vise is shown at5, Fig. 1. The operating lever 2 is provided with an adjustable screw 6which may be moved toward or from the adjacent'vise member 5. as condi-.tions may require. Ordinarily the screw 6 of the lever 2 is set in suchjuxtaposition to the jaw 5 that when the latter spreads and locks a lineof matrices, it will move toward the screw 6, and, under certainconditions, engage the latter and throw the lever 2 so as to rock thestop lever 3 and carry it clear of the pot pump lever 4 and allow thecasting movement of the same.

The present invention comprchends a means which may be introduced whenthe operator desires to prevent the casting of a slug from a line ofmatrices in the assembler. T he stop or controlling device in thisembodiment comprises a lever 7, pivoted at 8 upon a convenient portionof the machine frame, the lever having a handle portion 9 convenientlydisposed with relation to the position of the operator.- The handle,when pressed downwardly, lifts the-oppo site end of the lever, uponwhich is pivoted at 10 a dog 11, which is here shown as having a reducedend portionl2. When the handle 9 is pressed downwardly by the operatorthe dog 11 is elevated so that the thinner portion 12 is brought intoposition between the adjacent vise part 5 and the screw 6, so that thevise when adjusting will not engage the screw 6. Therefore the pot pumplever will beprevented from completing its cycle and no line will becast in the casting mechanism from the matrices assembled inthe vise.

During the continued operation of the linotype machine the line ofmatrices will be carried from the casting position and the lever orcontroller 7 remains in its noncasting or disconnected position until itis thrown by the operator to carry the dog 11 down into couplingposition, or until it is automatically thrown intooperative posit tionby its engagement with a shoulder 13 secured on a convenient portion ofthe assembler elevator 14s The assembler elevator 14 when movingupwardly with an assembled line of matrices causes the shoulder or tripdevice 13 to engage the adjacent portion of the lever 7, tilting itupwardly, and moving the dog 11 downwardly so that its thicker portionintervenes between the adj acent jaw 5 and the screw 6 of the operatinglever 2. Thus it will be seen that the coupler 7 is normally in such aposition that the dog 11 intervenes and transmits motion from the visejaw 5 to the-operating lever .2; the latter acting throughthe medium ofthe pot pump lever stop lever 3 to release the pot pump lever 4c andallow it'to'continue its functional movement.

When for any reason the operator throws the controller lever 7downwardly at the handle 9 to remove the dog 11 from interveningposition, then no slug would be cast from the line of matrices for thereason that the pot pump lever stop lever would be cleared. Then on theimmediately succeeding upward movement of the assembler 14 the shoulderl would be carried into engagement and throw the controller lever 7.This automatic operation occurs before the line of matrices in theassembler 14 is shifted to the line-casting position.

Oscillating movement of the lever is limited by suitable adjustablestops or screws 15 which engage the contiguous frame. Play of the lever7 is prevented by a friction washer or suitable device 16, shown here ason the pivot 8 and bearing on and holding the lever in place when raisedor lowered.

Having thus described my invention, what I claim and desire to secure byLetters Patent is I 1. In a line-casting machine, having pump mechanism,a matrix vise, an assembler and a device having a part interposablebetween said vise and pump mechanism for,trans: mitting movement fromthe vise to the pump mechanism, said device being manually movable toclear said members for non-transmission when it is desired to preventline castv and manually'shifta is from said position.

3. In a line-casting machine, an operating lever for the pump stoplever, the matrix line vise,'an assembler, and means with a partinterposable between said vise and operating lever to transmit motionfrom the vise to the lever, and manually shiftable from said positionand the assembler. 1

4. In a line-casting machine, an assembler, a vise member, and anoperating lever for the stop lever, means for transmitting motion fromthe vise member to the stop lever operating lever, said-means comprisinga lever with a dog manually movable to nontransmitting and mechanicallymovable by the assembler to transmitting position.

5. In a line-casting machine, in combination, with the vise and theoperating lever for the stop leverof the pump operating lever, a dogmovable to be interposed between the vise and the operating lever forthe stop lever for actuatingthe stop lever operating lever from thevise, and means for automatically moving the dog to interposed positionfor actuating said operating lever for the stop lever.

6. In a line casting machine, in combination with the operating leverfor the stop lever of the pump, the matrix vise and the assembler, meansoperated by the assembler to maintain connection between the operatinglever and vise to enable the operating lever to be actuated from thevise, said means being manually movable to disconnect the operatinglever from the vise.
